Logic to cause transmission of an audio protocol data unit (PDU) during each of the one or more subevents. Logic to generate a feedback request frame as a feedback request PDU. Logic to cause transmission of the feedback request PDU on a feedback channel. Logic to scan the feedback channel for one or more feedback response PDUs transmitted in response to transmission of the feedback request PDU. Logic to modify the one or more parameters of transmission of the audio PDUs in a subsequent broadcast isochronous group (BIG) event based on the one or more feedback response PDUs. Logic to receive of an audio PDU during each of the one or more subevents. Logic to receive the feedback request PDU on a feedback channel. Logic to generate a feedback response PDU in response. And logic to cause transmission of the feedback response PDU on the feedback channel.

Logic to cause transmission of a first generic attribute profile (GATT) advertisement comprising a first address associated with the service provider. Logic to generate a second non-GATT advertisement comprising a second address, an encoded personalized identifier (ID), and a payload comprising the first address. Logic to cause transmission of the second non-GATT advertisement. Logic to receive, from a scanner device, a request for the service associated with the first address. Logic to receive a first GATT advertisement for a service provider comprising a first address associated with the service provider. Logic to receive a second non-GATT advertisement comprising a second address, an encoded personalized ID, and a payload, wherein the payload comprises the first address. Logic to decode the encoded personalized ID and associate the personalized ID with the service provider. And logic to request, from an advertisement device that transmitted the first GATT advertisement.

Methods and arrangements for service advertisements

For example, a first Bluetooth (BT) device may be configured to operate in a role of a peripheral device over a BT link between the first BT device and a second BT device; and to initiate a role switch to switch the first BT device from the role of the peripheral device to a role of a central device over the BT link between the first BT device and the second BT device, based on a determination that the BT link between the first BT device and the second BT device is to be operated as an audio link to communicate audio data between the first BT device, as an audio source, and the second BT device, as an audio sink.

Apparatus, system and method of bluetooth role switch

A communication device is provided including at least one processor coupled between a wireless communication terminal interface and an audio source; and a memory having a personal audibility feature (PAF) file stored therein and coupled to the processor, wherein the processor is configured to provide an audio stream to the wireless communication terminal interface based on a processed audio signal, determined using the audio source, wherein the processing corresponds to the information stored in the PAF file, the PAF file comprising personal auditability feature of a predetermined user and an audio reproduction feature of a predetermined terminal hearing device.

Communication device, hearing aid system and computer readable medium

The present disclosure provides a controller configured to detect a reconnection single point of failure in a Bluetooth or other Low-Energy wireless connection attempt with a peripheral device and implement a procedure to reconnect with the peripheral device by delaying the reporting of the connection failure to a host processor. Instead, the controller initiates an additional scan on a different frequency band than used in the initial attempt in a further attempt at connecting with the peripheral device.

Methods and devices for connection retry after failed connection attempt in wireless systems

For example, a Bluetooth (BT) device may be configured to identify metadata in broadcast messages received at the BT device from a plurality of BT audio source devices, wherein a broadcast message from a BT audio source device includes metadata indicating one or more attributes of audio data broadcasted by the BT audio source device; and select from the plurality of BT audio source devices one or more recommended BT audio source devices for a BT audio connection, the one or more recommended BT audio source devices selected from the plurality of BT audio source devices based on the metadata in the broadcast messages and based on a user profile corresponding to a user of the BT device, the user profile including personalized preference information corresponding to a preference of the user for selection of audio content.

Apparatus, system, and method of bluetooth audio source selection

Methods, apparatus, and computer-readable media are described to encode, by a first station (STA), a polling signal for periodic transmission to a second STA during each air activity instance of a plurality of air activity instances. The first STA detects an interface between a MAC layer and a software stack of a communication protocol is in a low-power state. The communication protocol is associated with a communication link between the first STA and the second STA. An empty packet from the second STA is decoded. The empty packet is received in response to the polling signal transmitted during an air activity instance of the plurality of air activity instances. The periodicity of the periodic transmission of the polling signal is adjusted based on the detected low-power state and the decoded empty packet.

Idle connection optimization for wireless devices

Methods, apparatus, systems and articles of manufacture to improve Bluetooth low energy streaming connection efficiency are disclosed herein. An example method includes accessing a request received at a first device from a second device, the request requesting set up of an isochronous link between the first device and the second device, the request including a configuration identifier. Whether the configuration identifier identifies a configuration stored at the first device is determined. In response to determining that the configuration identifier identifies the configuration stored at the first device, the isochronous link using the stored configuration.

Methods and apparatus to improve Bluetooth low energy streaming connection efficiency

This disclosure describes an enhanced Bluetooth channel establishment. A device may identify an isochronous connection oriented (ICO) command for a Bluetooth communication. The device may send a first ICO start command from a first link layer (LL) to a second LL, and the first LL may receive a first ICO start confirmation from the second LL. The first LL may then send a second ICO start command to a third LL, and the first LL may receive a second ICO start confirmation from the third LL. A third ICO start confirmation may then be sent. The device may also have an ICO request and response exchange between LL's.

Enhanced bluetooth channel establishment

In situations in which a given communication device may be a slave node on multiple communication sub-networks, a communication resource of the communication device may be allocated so as to serve the various sub-networks according to a device-centric control protocol.
